Cisco IOS Basic Commands

This tutorial is my very first tutorial. Please post comments on how I could improve.

Router&gt; - Your in user mode right now, you can always tell your in user mode by the ‘&gt;’

Router&gt;enable - the 'enable' gets you to the privileged mode

Router# - Your in privileged mode now, you can always tell your in privileged mode because of the ‘#’

Router#show running-config - 'show running-config' lets you see the running configuration you have on the router, plus it shows you the version of the IOS

Router#show clock – ‘show clock’ lets you see the time that you configured on your device

Router#show history – ‘show history’ shows you the log of the history you typed in so far.

Router#show version – ‘show version’ shows you the version of your IOS and other neat things as well. It also shows you how long the up time has been, which interfaces are on the device. Plus, lots more.

Router#show interfaces – ‘show interfaces’ shows you all the interfaces and if there down or up, and other things as well like the MTU (Maximum Transmission Unit), how many packets were received/sent.

Cream(config)#interface ethernet0 – ‘interface ethernet0’ this is a little different in which it changes to a whole different mode, The interface mode, It changed to the interface ethernet0. You might have serial0 or ethernet1 to put in place of ethernet0. It depends on which one you want to configure.

Cream(config-if)#no shutdown – ‘no shutdown’ no shutdown puts it in the up state. Before it was in the down state which meant ethernet0 was nothing to the router.
